Sarah Louise Treacy was born on 22 June 1989 to Liam and Siobhan, both former international distance runners. Siobhan ran in three World Cross Country Championships. Treacy started training when she was seven or eight years old, and her parents would only let her train for one night a week because they thought she was too young for a more intensive training regimen. When she was a little older she trained with the Moynalvey-Kilcloon AC. She also tried football and hockey, but towards the end of her secondary school career at The King's Hospital decided to focus on athletics. Her first international competition was the 2006 World Cross Country event in Fukuoka, Japan. She competed in the 6000m and finished in 69th place. Treacy's experience there encouraged her to commit to training. She considered leaving for the United States to train, but decided not to after sustaining an injury.
